Here's my spreadsheet that I used to analyse last year's data from SpectrumLab. I just counted the hourly totals manually.
My view is that false detections will be of two kinds: Totally random, that just lift the baseline, and missed or double detections which will be random but proportional to the amount of meteors. Neither of these has a significant impact on the proportionality of the readings, so take the absolute numbers with a pinch of salt, although inspecting screen captures suggests there are few false detections.
As no detection setup will get more than a percentage of meteors and it's impossible to be sure exactly what your area of search is, I think the only scientifically valid result for is comparing readings at different times with the same location and setup (and possibly weather). That said it's interesting to compare detections of really big meteors and to note things like ISS and plane passes.
